LITTLE FALLS, NEV YORK.

PAPER-FEEDER.

SPECIFICATION forming' part of LettersI Patent No. 434,643, dated August 19, 1890.

Application filed October 16 1886.

To all whom it may concern:

Be it known that I, J AMES NAYLOR, Jr., of Poughkeepsie, in the county of Dutchess and .State of New York, have invented new and useful Improvements in Paper-Fee'ders, of

which the following is a speoification.

This invention relates to that class of paper-feeders which feed sheets. of paper successively from the top of a pile to a ruling, folding, or calendering machine, printingpress, orother machine in which Sheet-paper is used. These machines consist, essentially, of a pile-supporting bed or table, which is automatically raised as the paper is fed off, devices whereby the top sheet is buckled or loosened, and devices whereby the loosened top sheetjs fed off.

The object of my invention is to produce a simple and reliable machine of this kind, which will operate with eertainty and which can be easily adjusted to feed paper of different sizes. o g

Myinvention consists of the improvements which will be hereinafter fully set forth, and pointed out in the claims.

In the accompanying drawings, consisting of five sheets, Figure l is a side elevation of my improved paper-feeder. 'Fig. 2 is a rear elevation thereof. Fig. 3 is a top plan View thereof. Fig. 4 is a sectional elevation in line a; x, Fig. 3, looking outward. Fig. 5 is a cross-section in line y-y, Fig. 4. Fig. 6 is a sectional rear elevation of the buckling and holding-down meehanism. Fig. 7 is a longitudinal sectional elevation of the feeding-fingers and feedro'llers. Fig. 8 is a sectional elevation showing the connection of the rear side guide with the support-ing-bar of the holdingdown finger. Fig. 9 is a Vertical cross-section of the mechanism whereby the feed-serews are actuated. Fig. 10 is a longitudinal section of the upper feed-rollers. Fig. 11 is a sectional elevation of the mechanism by which the feed-sorews are actuated, the section being taken at right angles to Fig. 9 and looking outward. Fig. 12 is a perspective View of the lower end of the pawl-lever. Fig. 13 is a seetional view showing the pawl in engagement. VFig. 14 is abottom plan view 50* of the feed-table. Fig. 15 is a seetional elevation of one of the lugs of the feed-table on Serial No. 216.353. 4(No model.)

an enlarged scale. Fig. 16 is a top plan view of the buckling and holding-down Iingers. Fig. 17 is a sectiona-l elevation of the forward side guide. Fig. 18 is a horizontal section through the lower part of the side frame to which the side guides are attached. Fig. 19

is a top plan View of the pawl-lever, showing the same arrested by the automatic stop. Fig. 20 is a similar view showing the pawllever released. Fig. 21 is a sectional View of the buckling-iinger on its return-stroke.

Like letters of reference refer to like parts in the several figures.

A A' represent the upright side frames of the machine, connected at the bottom by cross-Stays a a and at the top by cross-Stays a' (L2. The side frames A A' rest upon trans verse rails ai, which are secured to the floor and whichenter grooves in the feet of the side frames, as represented in Figs. l and 2, so that the machine can be readily moved 'laterally to adj ust its position with reference to the ruling or other machine in connection with which it is used.

A2 represents a standard secured to'` the floor on one side of the machine between the rails (1.3, and w* is a horizont-al adj usting-screw, which is journaled in the standard A2 and works in a threaded opening in the adjacent side frame, so that the machine can be nicely adjusted on the rails by tnrning the screw at B B' B' represent the Vertical feed-screws by which the bed or table B2 is ra'ised and lowered. The screw B is arranged oni'the in; ner side of the frame A at ornear the middle thereof, and the screws B' B' are arranged on the inner side of the side frame A' near the frontand rear ends thereof, as clearly shown in Figs.1,2, and 3. The screwBis journaledatits upper and lower ends, respectively, in bearings b b', seeured to the inner side of the frame A, and the screws B' B' are journaled in bearings 212 (23, secured to the frame A'. The bed or table B2 is supported by the feed-screws B B' at three points, whereby the table can be freely raised and lowered without binding on the feed-screws, although t-he paper is piled on the table out of center or at one side of the machine near the side frame A, as shown at roc B3. The feed-table rest-s losely upon screw-v nuts c, which are applied to the feed-Screws B B' and which enter' recesscs or soekets c' in the under side of lugs O C', formed on the feed-table, as shown in Figs. 1, 14, and 15. The screw-nuts are made square or otherwise so shaped that they are prevented from turning when seated in the correspondinglyshaped reeesses c' of the feed-table. Upon raising the feed-table so as to disengage its reeess c' from the screw-nut con which it rests the screw-nut can be turned on the feed-screw, therebyaifording means for raising or loweringeaeh side of the feed-table independently, as may be necessary for the purpose of levelin g or adj nsting the table.

(Z represents a bevel-whecl seeured to the feed-screw B near the upper end thereof and meshing With a bevel-wheel d', which is secured to the inner end of a horizontal shaft d2, journaled in the upper portion of the frame A.

D is a wheel secured to the outer end of the shaft (12 and provided with a handle da, so that it can be turned by hand.

e e' e' represent sproeket-wheels secured, respeetively, to thelower portions of the feedserews B B' B', and 82 is an endless chain running around the sprocket-wheels e e' e',whereby the motion of the feed-serew B is transmitted to the screws B' B' E represents a tightening-block adjustably attaehed to the lower portion of the side frame A' by a slotted arm E', as represented in Fig. 3, and bearing against the outer side of the chain 82 between the Wheels e' c', so as to maintain the proper tension of the chain. Upon turning the shaft (12 in one or the other direction the three feed-screws are turned simnltaneously, so as to raise or lower the table B2. This arrangement of the screws and their driving mechanism simplifics the construction of the machine materially. lt dispenses with the Vertical guides and anti-friction rollers usually employed for guiding the table in its Vertical movement on the main frame and imparts greater steadiness to the table. It permits all of the screws to be made righthanded and admits of eomparatively coarse threads on the feed-screws.

The wheel D, by which the feed-'screw B is actuated, is provided on its rear side with an annular groove f, arranged concentric with the'axis of said wheel.

F represents a pawl-lever whereby the wheel D is actuated, and which rests with its upper and free end upon an eeeentric or cam f', while its lower end is provided on its front side with a curved rib or pawl 2, which enters the groove f of the wheel D. The pawl f fits loosely in the groove f, so that it can be moved back and forth in the same without moving the wheel D, except when the leverisine1ined,so as to cause the pawl to bind against opposite sides of the groove, as represented in Fig. 13, when the Wheel is moved by'the pawl in the direetion of the arrow. This movement of the wheel causes the feedscrews to raise the feed-table. The groove f and the pawl f2 are made of dovetail form in cross-section, as represented in Fig. 9, whereby the pawl is caused to hug the disk of the wheel during its movements, thns preventng the pawl from eseaping from the groove, a though the latter is so large as to permit the pawl to be inserted and removed.

g is a finger, which is seoured to the rear side of the aetuating-lever F near the lower end thereof, and which is adapted to engage against the lowerarm g' of a bell-crank lever G. The latter is pivoted to the side frame A underneath the shaft cl2 of the wheel D, and swings in a plane at right angles to the movement of the aetuating-lever F. The upper arm g2 of the lever G projects over the pile of paper, and its position is Controlled by the height of the pile in such manner that the upper arm 92 descends and the lower arm g' moves outward as the height of the pile decreases. Vhen the lever G is in its normal position, which is the case when the feed-table presents the top sheet of the pile properly to the mechanism by which the sheets are removed, the lower arm g' stands in'the way of the finger g, as represented in Fig. 19, and prevents the arm F from descending to the lowest point of the groove f. In this position of the arm F therocking movement, which is imparted to it by the cam has` no effect upon the wheel D and the feed-table is not moved. Then the height of the pile is so much reduced that the feed-table is required to be raised, the upper arm gzdeseends so far as to cause the lowerarm g' to swing outward far enough to clear the finger g, as represented in Fig. 20. In this position of the'lever G the level' F descends at every stroke to its lowest position, as represented in Fig.11, and (luring its upward stroke, which is effected by the eccentric f the pawl f2 binds against opposite sides of the groove f and turnsthe wheel. The latter is turned in this manner by a succession of movements of the lever F until the feed-table has been raised to its normal position, whereby theupper arm (12 of the lever G is raised accordingly, and the lower arm g' is moved inwardly to a position in which it arrests the downward movement of the lever F by coming in contact with the finger g; The eccentric f' is seeured to a horizontal shaft h on the inner side of a gear-wheel H, which is driven by an idler II' from a gear-wheel 112, secured to the shaft h' of the lower taperoller Hg.

The downward movement of the lever F may be effected solely by gravity; but I prefer to aecelerate its downward movement by means of a spring which is applied toarod and which bears against the rear side of IIO the frame A, as represented in Fig. 1. The

opposite end of the rod i' is connected with the lower end of the lever F, as represented in Fig.11. The outer end of the rod /i'is provided with a screw-nut i, by which the pressure of the spring may be regnlated.

J represents the movable frame to which depending from the ends thereof and rigidly j and rotated by bevel-wheels 7.: k'.

secured thereto, as clearly represented in Figs. 3 and 4. The rodj is guided in lugs l72 14, projecting inwardly from the top Vportion of the side frame A, and the lug t7'4 is provided with a set-screwj, by which the frame J can be secured in position after it has been adjusted. i

K represent-s a horizontal 'haft journaled in the arms j' ,7'2 of the frame J below the rod The wheel e is secured to the inner end of the shaft h, by which the actuating-lever F is operated, and the wheel 7a' is mounted on the shaft K by means of a groove and feather, so that the shaft K can move'through the wheel k' in adjusting the frame J on the machine. The wheel k' is held against longitudinal displacementbetween the inner end of the shaft hand the upper cross-stay a'.

Zrepresents a cam secured to the rear end of the shaft K, and L is an arm pivoted with its upper end to the rear arm j2 of the frame J, so as to be inoved in one direction by the cam Z and in an opposite direction bya sprin g l', as represented in Fig. 2.

L' represents the buckling-finger, by which the ,top sheet of the pile is loosened, and which is connected with the lower end of the arm L by a link or rod L2. The finger L' consists of a rough or adhesive portion Im, which bears against the paper and moves the same during the operat-ive or forward movement of the finger, and a smooth portion m', which slides over the paper during the return moveinent of the finger and does not move the same. The rough portion m of the finger is preferably formed by a block of rubber, which is secured by a removable cap m2, while the smooth port-ion fm' is preferably constructed of metal. The finger L' is pivoted at its upper end to the rod L2, and rests with its lower curved surface upon the pile near the outer rear corner thereof. When the arm L is swung backwardly by the cam Z, the finger is rocked on its base by the rod L2, so as to bring the rough front portion m of 4the finger without moving the top sheet.

in forcible contact with the paper, as represented in Fig. 6, whereby the top sheet is buckled or loosened. Upon the reversal of the movement of the arm Lthe finger L' is rocked in an opposite direction, so as to bring the smooth portion 'nt' in contact with the paper, as represented in Fig. 21, whereby the finger is enabled to effect its return-stroke The downward 'pressure of vthe finger L' against the paper may be increased by a spring m3, which 'is applied to an upright rod 'm4 and abuts against a bracket m5, secured to the rear-arm j2 of the adj ustable frame J. The lower end of the rod' 'm4 is attached to the rod L2, while its upper end passes loosely through the bracket m5. The tension of the spring is regulated by a screw-nut m on the rod m4.

erts the greatest pressure upon the finger at this point of its movement, while the pressure grows less as the finger moves out of this position in either direction.

. N represents the outer holding-down finger, whereby the corner of the pileis held down near the edge thereof. This finger is pivoted at its outer end in a lug a, secured to the upper end of the rear side guide 'n'. The lug n is provided in its upper side with a recess, in which the finger N is pivoted by a horizontal rod 712. finger N is made in-clined, so as to rise out- Ward, as represented in Fig. 6, land the inner end of the finger is provided with a pivoted bearing-piece nt, which rests upon the paper. O represents the inner holding-down finger,

corner thereof at a short distance inwardly from the outer finger N. The finger O is attached to a rod O', which is pivoted at its outer end to the rod n2, upon which the outer finger N is pivoted. The inner end of the rod O' is connected by an arm O2 with the rear end of a shaft p, to which the arm O2 is rigidly secured and from which it projects inwardly.

O3 is an arm, which is also secured to the rear end of the shaftp and which projects outwardly therefrom,its outer end being located over the outer finger N. The outer end of the arm O2`carries a grooved roller or stud O4,Whieh is adapted to bear upon the inclined back of the finger N. The shaft p is arranged in the adj ustable frame J below the shaft K, and is journaled with its front end in the armj', while its rear end is capable of a limited vertical movement in a' slot p' in the arln j2, as represented in Fig. 4.

P represents a cam or eccentric secured to the front end of the shaft K, and P' is a bifurcated arm secured to the front end of the shaft p below the eccentric P and engaging therewith, as represented in Fig 5, whereby a rocking motion is imparted to the shaft p. The arms O2 O3 take part in this rocking motion of the shaft p, one arm rising when the other descends. The cams land P are so arranged upon the shaft K that the cam Z causes the buckling-finger L' to move toward the inn'er holding-finger O in the direction of the press the arm O2 and raise the arm O As the inner holding-finger O rests upon the pile, the arm O2 cannot be depressed, and the rockwhich rests upon the pile near the outer rear arrow in Fig. 6, when the cam P tends to de-V The rod m4 is Vertical when the finger L' vis in the middle of its stroke, whereby the spring is compressed to the'greatest extent and ex-l The upper edge of the IOO IIO

ing motion imparted to the shaft p by the cam P and arm P' causes the shaft p to be 'raised on the inner end of the arm O2 as a the front end of the shaft, at which the shaft is loosely journaled. The ascending movement of the shaft 1) raises the outer end O4 of the arm O3 from the outer holding-finger N, thereby relievin..r the latter from pressure and enabling the buckling-finger L' to move the corner of the top sheet from under the outer finger N in buckliug it against the inner finger O. When the movement of the shaft 1) is reversed, the arm O3 descends until it rests with the roller O4 upon the outer finger N. The continued roeking motion of the shaft p in the same diroction causes the shaft to be raised on the outer end of the arm Oa as a fulcrum, thereby raising the inner holding-finger O from the pile and releasing the top sheet. Inl this manner one of the holding-down` fingers is always held down upon the pile, as neither finger can be raised, exceptafter the other finger has secured a firm bearing upon the pile.

112 represents a pointed guard, which is hung loosely on the arm O3 on the inner side of the finger N, and which rests upon the pile and prevents the loosened top sheet from passing under the outer finger N during the return-stroke of the buckliugfinger. The inner holding-finger O is adjustably secured to the bar O' by a set-screw or other suitable means. The position of the rock-shaft p is controlled by the fingers N and O, which rest upon the pile. Vhen the top of the pile sinks below the normal position, the shaft p sinks also, and this movement of the shaft is transinitted to the lever G by the upper arm g2 of the latter, which straddles the shaft p, as shown in Fig. 9, while anascending movement of the pile causes the shaft 1) to rise and moves the lever G in an opposite direction. In this manner the positioniof the shaft p is regulated by the height of the pile, and the actuating-lever F is automatically re' leased or arrested by the lever G, as the maintenance of the normal height of the pile may render necessary.

q represents the upright front guides against which the paper is piled, and which are rigidly secured to the upper cross-piece 0,2 and the lower cross-piece a, as reprcsented in Fig. 2.

q' represents the front side guide secured to the inner side of the frame A near the front endthereof, and provided at its upper and lower ends,respective1y, with perforated lugs (12 Q3.

q* represents a horizontal rod by which the lower ends of the side guides q? and n' are supported. The rod q4 passes loosely through lugs Q5 (16, formed 011 the inner side of the lower portiou of the frame A, as reprcsented in Fig. 18, and is clamped in these lugs by a set-screw Q7, which passes through the frame A and bears against the lower lug (13 of the forward side guide q', so as to spring the rod Q4 and bind it in the lugs Q5 q. Upon releasing this set-screw the rod Q4 can be adjusted forwardly and backwardly to correspond with a similar adjustment of the frame J. The upper end of the forward side guide q' is similarly seeured by a set-screw (18, bearing against the upper lug Q2. The upper lug n of the rear side guide n'is attached to the rod by a screw q, which passes through a seglnental slot (11 in the rod and enters the lug, as shown in Fig. S. By this means the rear guide a' is caused to take part in the adjustment of the frame J, and is therefore always in the proper position to support the outer rear corner of the pile. The lower end of the guide n' is provided with a perforated lug nt, which slides upon the lower rod qi. The upper hor'zontal rod m2 is loosely supported in lugs q11 q, formed on the upper `portion of the side frame A, in which lugs the rod is clamped by the set-screwv qa. The rods 1x2 and q? are easilyadjusted backwardly or forwardly to correspond with the position of the adjustable frame J.

1' represents the transverse horizontal rockshaft by which the fingers R are actuated, which move the loosened top sheet from the pile. Each finger R is connected by a rod or' link R' to an arm R2, which depends from the rock-shaft r. Each finger R is pivoted to the front end of its rod R', and is provided with a rough pushing surface r' and a smooth retreating surface T2, corresponding, respectively, with the rough and smooth surfaces m m' of the buckling-finger L'. The fingers R bear upon the paper with their rough surfaces 0"' during their forward movement and push the top sheet out, while they slide over the paper on their smooth surfaces 'r2 during their return movement. The rock-shaft 0' is actuated in one direction by a cam 73, mounted upon the inner end of the shaft h and engaging against an arm T4, and is returned by a spring W when released by said cam. (See Figs. 3 and 7.) The lower feed-roller 113, mounted upon the shaft h', is driven by a sprocket-wheel S, secured to said shaft and connected by an endless chain with the ruling or other machine to which the paper is fed, thereby maintaining positivcly the proper relative movement of both machines. i

S' represents the feed-tapes, which run around the lower roller Hs.

T represent-s the upper feed Wheels or rollers, which are arranged above the lowerroller Hiand run in contact with the upper surface of the paper. The rollers T are secured to a tubular shaft t, which is driven by means of a flexible shaft oi' rod t', passing through the tubular shaft t, as reprcsented in Figs. 7 and 10. The tubular shaft t is held in slotted bearings 62, which are secured to the cross- Vstay a' and permit a limited Vertical movement of the shaft t, thereby enabling the rollers to adapt themselves to any inequality in the surface of the paper or lower feed-roller. The inner driving-shaft t' is made so thin that it springs or bends as the feed-Wheels rise or fall, thus providiug a positive driving me'chanism for the upper feed-Wheels within the limits required for their vertical niotion. The driving-shaft t' ispreferably made square and passes through a socket 253, secured centrally in the tubular shaft t, and having a square opening, which is slightly enlarged toward both ends to permit the shaft t' to spring or bend. When the sheets of paper are very wide, two or more tubular shafts t, provided with feed-Wheels, may be arranged upon the shaft t'.` The latter is driven from the shaft h' of the lower roller' by a gear-wheel tt, mounted on the shaft h', and a gear-wheel 255, having a hub with a square opening,in which the shaft t' is seated. By thus driving the upper feed-Wheels the slipping of the Wheels on the paper is prevented, which will take place when frictional contact is relied upon for driving the upper Wheels from the lower roller through the intervening sheet of paper, and the excessive pressure formerly applied to the upper Wheels is avoided.

The link of the buckling-finger L' and the links of the feeding-fingers R are each provided with an opening 'u,, in which can be secured a lifting-string. These strings run over suitable rollers arranged overhead and terminate in convenient reach of the operator,where they are attached to a suitable ring or handle, by which all of the fingers can be raised simultaneously from the paper for stopping the feeding of paper without stopping the moving parts. The upper rod R2, to which the inner holding-finger O and the outer finger N are both pivotally connected, is arranged somewhat higher than the top of the pile and the bearing-surfaces of the fingers. These fingers therefore tend to draw the paper toward the side guides, and cause the pile to rest closely against the side guides at all times and counteract the tendency of the bucklingfinger L' to move the pile away from the side guides.

My improved paper-feeder is especially desirable for use' in small establishments in which a feeder is required for job work and where the feeder must be frequently adj usted to operate upon small quantities of paper of different sizes.

I claim as my invention- 1. In a paper-feeder, the combination, with the feed-screw, of a screw-nut mounted on said feed-screw, and a feed-table resting loosely on said screw-nut and provided With a socket in which the screw-nut is held against turning, substantially as set forth.
